"Second blood test as first wasn't done correctly"

Sitting around in a hospital waiting area for a blood test that should have been done properly the first time around and being fleeced in the car park for my time is not how I envisaged spending my day off.

But that is what I am doing. According to my GP the first blood test was done incorrectly (they did not use an immunology tube as instructed), I am now having to go back and get a second one done.

He has written it on the chit in capital letters.
